COUPLING.

SPECIFICATION forming part of Letters Patent No. 707,991, dated August26, 1902.

Application filed April 18, 1901. Serial No. 56,491. (No model.) j

T all whom, t may concern:

Be it known that I, FRED A. WAREHAM, a

citizen of the United States, residing at East Y or coupling withoutscrew-threads or additional fastenings; second, to provide a washerl ofa shape` adapted to render the connection water-tight; third, to providea grippingflange to assist'in detaching the coupling,

and, fourth, to protect the parts from injury as much as possible byinterior construction and non-corroding materials. I attain theseobjects by themechanism illustrated in the accompanying drawings, inwhich- Figure 1 is a side elevation of the coupling with the membersseparate. Fig. 2 repre-j sents the parts together. Fig. 3 is alongitudinal section of the entire coupling with the parts together.Fig-4 is a central longitudinal section of the female member 2. Fig. 5

' and Fig. S is a perspective view of the post.-

is a cross-section in Y Y, Fig. 4, of the female member 2. latch. Fig. 7is an edge view of the latch,

Similar numerals refer to similar parts throughout the several views.

The hose is attached to the male member 1 and the female member 2 at 3and 4, respectively, in any usual way, (see Fig. 1,) or the male member1 and the female member 2 form, respectively, the ends of the pipe to becoupled or joined in the longitudinal direction X X of the parts 1 and2, Fig. 1. The male member 1 is formed with the outside surface slightlytapering at the entering end 5 and with an annular groove 6 cut in suchoutside surface a short distance from such entering end, with thebearing portion 7 of such groove formed straight and vertical to receivethe inside Fig. 6 is a top plan View of they projecting ends 8 of theposts 9 (see Figs. 3 and 8) of the locking device of the female member 2when locked in position and allowing the two parts of the coupling torevolve on each other when so locked in position. (See Figs. 2 and 3.)The male member 1 is provided still farther from such entering end 5with a buffer 10, milled on its outside circu inference to bring upagainst a similar buffer 11, also milled on its outside circumference onthe receiving end of the female member 2 when the two parts of thecoupling are locked in position ready to revolve on each other. Thefemale member 2 isprovided with a round chamber 12, Fig. 3, tofreceivethe entering end of the male member 1, the washer .13, and theprojecting end 8 and face 14 of.

the posts 9 of the locking device entering into the annular grooveY 6 ofthe male member 1 when the two parts of the coupling are locked inposition. The back of the chamber 12 is vprincipally straightandvertical to receive snugly the similarly straight and vertical flange17 of the washer 13, but is provided at its outside circumference with-asmall annular 'groove 15, forming a rectangular recess for the receptionof the outer circumference 16 of such flange 17 of the washer 13 and toprevent such washer 13 from falling out of the female member 2 when thetwo members are detached, Figs. 3 and 4. The back of the chamber 12 isalso provided, as shown in Fig. 3, with a slight tapering or sharpenedcircular projection in the general longitudinal direction X X, Fig. 1,of the hoseor pipe for the purpose of pressing into such flange 17 ofthe'washer 13 and alone or Vin conjunction with the pressure on thewasher 13 of the contents passing through the hose or pipe to form awater-tight coupling or connection. The washer 13 is constructed of"soft pure rubber or similar substance and is elongated at right anglesto its flange 17, Fig..A 3, and slightly tapering at itscircumference'35, so as to pass within the entering end 5 of the malemember 1 when the two parts of the coupling are lockedin position, andall forming awatertight coupling or connection, as hereinbefore stated,while still allowing the male member 1 and the female member 2 torevolve on each other.

Atopposite places on the outside circum- IOO ference of the femalemember 2 the surface is thickened in the longitudinal direction X X,Fig. 1, of the hose or pipe to allow room for the construction of thelocking device, and the connecting-angles are not sharp,.but rounded, soas to prevent injuryin handling and any accumulation of dirt or othersubstances, Fig. 5. The locking device consists of two or more latches19 on opposite sides of the exterior of the female member 2, Fig. 3,forming movable portions of the exterior of such female member 2, eachlatch hung at about its middle upon a pin 20, running through ahorizontal circular hole 2l cut at right angles to the generallongitudinal direction X X, Fig. l, of the hose or pipe in the exteriorportion of the thickened part of the female member 2, as shown in Fig.3, Fig. 4, and the cross-section of Fig. 4 at YY shown in Fig. 5, oneend of/ each latch slightly convex and under such end of each latch aspring 22 held in a small spring-chamber 23 of the female member 2, suchspring serving to hold the outside edges of each latch even with theexterior adjoining surface of the female member 2, Figs. 3 and 7. Eachlatch is provided with a small projecting lug 24, Figs. 6 and 7, withits horizontal bearingsurfaces rounded, such lug working into ahorizontal circular receiving-hole 25 of the post 9, extending partly orentirely through said post 9 or workinginto a horizontal grooveextending partly or ent-irely across the face of such post 9, whichtouches the latch 19, but not permanently fastened in such hole orgroove, Figs. 3, 6, 7, and S. The two posts 9, or the posts 9 formingpart of such locking device and being also movable portions of theexterior of the female member2, (see Fig. 3,) extend each through avertical fitting-hole 26 of the female member 2, Figs. 3 and 4. Eachpost projects into the receiving-chamber 12 of the female member 2, andwhen the two parts of the coupling 1 and 2 are locked together inposition its projecting end S, formed straight and vertical, restsagainst the bearing portion 7 of the annular groove 6 of the malemember 1. The side 27 of such post 9 toward the male member 1 is formedrounded vertically, the side 28 away from the male member l is formed(continuing its projecting end S) straight and vertical, and the sides29 and 30 are formed parallel and vertical, Fig. S. The face 14,projecting into the chamber 12, is formed slightly hollowed, so as toiit the annular groove o' of the male member 1 and sloping from its endS to its end 3l, Fig. 3, toward the interior surface of the roundedchamber 12 of the female member 2 and adapted to receive the end 5 ofthe male member l when entering the female member 2, and permit such end5 to be pushed along into the female member 2 until the post 9 entersthe annulargroove (i of the male member 1, and the projecting end S ofsuch post 9 rests against the side 7 of such annular groove 6,

and the two parts of the coupling are automatically locked in position.

On the exterior of the female member 2 and slghtlybeyond the latches19,away from them in the general longitudinal direction X X, Fig. 1, ofthe male member 1, the circumfel'- ence of the female member 2 is raisedby a vertically-projecting iiange 32, Figs. 1, 2, and 3, slightlyroundedon the edge 33, where the female member 2 is not thickened, with itsconnecting-angles rounded and milled on its outside circumference,forming a grippingflange to assist in detaching the two couplings. Thelatches 19 when simultaneously pressed toward the interior of the femalemember 2 into their latch-chamber 34 by the simple pressure of one handof the operator readily and without the intervention of any other agencyoperate as levers to raise the posts 9 out of the annular groove of themale member 1, Fig. 3, and permit the operator, with the other handpulling against the gripping-flange 32 of the female member 2, toseparate readily and so disconnect the tWo parts of the coupling.

All parts of the coupling are constructed of non-corroding materials.

In constructing the spring 22 it may be of different forms, and it mayalso be placed in the latch-chamber 34 without constructing any specialspring-chamber 23.

What I claim as my invention, and desire to secure by Letters Patent,is-- 1. In a coupling, the combination with a male member having atapering end and an inclined contracted portion forming a verticalshoulder, of a female member having an annular chamber therein engagingsaid end ot" the male member, the rear Wall of said chamber yhaving anannular groove therein, an annular washer carrying a ange, the iiangebeing secured in said groove in said chamber and being engaged by saidtapering end ofthe male member, the washer engaging the innercircumference of the male and female members, enlarged portions onopposite sides of said female member having vertical openings therein,posts having lower inclined faces for engagement with said taperingportion and said shoulder of the male member, the upper ends of saidposts having horizontal openings therein, a latch secured to each ofsaid enlarged portions in an opening provided therefor on the upper faceof the enlarged portion, a pin passing through said latch and secured insaid enlarged portions, a rounded lug formed integral with one end ofthe latch and normally mounted in said horizontal openings in the posts,the other end of said latch being convex in cross-section forming a seaton its under face and a thumboperating member on its upper face, and aspring engaging said seat and in an opening provided therefor on theupper face of said enlarged portion, an annular fiange formed integralwith each end of the female member,

IOO

said chamber in the female member, the rear wall of said chamber -havingan annular groove formed therein, a projection formed at v the lower endof said groove, a Washer having an elongated portion for engaging withthe inner `circumference of'said male and female members, said Washercarrying a flange for engagement in ysaid groove in said chamber andsaid projection, the otherface of said iiange being engaged by saidtapering end of the male member, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
